Excel 2007 : Excel 2007 and SAP downloads

My ERP system is SAP. Every month, we download budget versus actual information for analysis. The data feeds to a summary spreadsheet. To locate new general ledger account numbers that come on during month, we have a list of standard account numbers in column A in Excel 2007. We copy and paste the data out of SAP. We then check to see if new account numbers have come into play by scanning down Column A and making sure the account number in that column matches the account number in the column just downloaded.

A very manual effort to say the least.

If the account numbers don't line up, we have to figure out what was added.

Is there a simpler way to do this? I've attached an example.
